Abstract: A shift register, a driving method of a display panel and related device. The shift register adds a selection output unit and a selection control signal terminal to the current shift register; the output terminal of the selection output unit outputs a signal that is same as the signal of the driving signal output terminal when the selection control signal terminal receives a selection control signal. Then whether there is a scan signal outputted from the selection driving output terminal is determined by the control of the selection control signal terminal and the selection output unit. Further, in using the gate-driving circuit consisting of the above shift register, selectively outputting scan signal to certain gate lines can be achieved. Further, in using said gate driving circuit in the display panel of the present disclosure, arranging three neighboring gate lines as a set of gate line along scanning direction and each set of gate line receiving scan signal sequentially along the scanning direction may be realized.
